`IMPROVEMENT IN SPINNING-WHEELS.

Specification forming part of letters Patent No. 154,969, datedSeptember 15, 1874; application led Y March 10, 1874.

To all whom it may concern:

Be it known that I, W. B. WALKER, of Cherokee Station, in the county ofCrawford and State of Kansas, have invented a new and useful Improvementin Spinning-Frames and do hereby declare that the following is a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had to theaccompanying drawings, forming part of this specilication.

My invention relates to improvements in spinning-frames, the object ofwhich is to provide a simple and effective apparatus for the purpose ofreleasing the spindle when it is desired to cross the driving-band fortwisting; and 4it consists of the combination, with the spindle-rest, ofa sliding bearing-box, constructed and operating as hereinafterdescribed.

A represents the frame of the machine; B, the driving-wheel, whichcommunicates motion to the multiplying-hub C of the wheel D, having anadiustable support in the upper end of the post E working on a pivot onthe end of the girt F. G represents a band working in a groove in thewheel B, and extending to and working in a groove in the hub C, alighter band running in a groove in the wheel D, and

y passing around the whirl on the spindle and extending to and workingin a groove in a wheel on the post opposite the driving-wheel B. Hrepresents a contracting and expanding Y frame, composed of two seriesof toggle-arms joined together by toggle-joints, the two series rivetedtogether and operated by a swinging lever, I, which derives its motionfrom foottreadle J, rocking over the foot of the post on which thedriving-wheel B is supported.

The support of the wheel Din the upper end of the post E working on apivot below, is for the purpose of tightening or loosening the bands atpleasure.

The said frame H is connected at one end of the frame of the machine. Onlthe other end is a spool to carry it back and forth on the frame ofthemachine. At this end of the frame the spindle-rest K is fastened. Thisrest is formed with a sliding box, L, held in position by a pin, a.

When it is desired to change the direction of the band on the whirl,this can be easily done by simplyT withdrawing the pin a and sliding thebox L along the spindle to the whirl. The spindle may `then be tippedslightly in its front bearing, so that the drivingband may be easilypassed over its rear end, and returned again to the whirl and crossed inthe opposite direction. The box may then be returned to place again.

What I claim as new, and desire to secure by Letters Patent, is

The combination, with the spindle and its rest K, of the box L, capableof sliding toward the spindle-whirl, and held in position by the pin a.,all substantially as and for the purposes set forth.

W. B. WALKER.
